In a home laundry dryer, a cylindrical tub containing wet clothes is rotated steadily about a horizontal axis as shown in the figure below. So that the clothes will dry uniformly, they are made to tumble. The rate of rotation of the smooth-walled tub is chosen so that a small piece of cloth will lose contact with the tub when the cloth is at an angle of e = 61.5° above the horizontal. If the radius of the tub is r= 0.425 m, what rate of revolution is needed? rev/min Additional Materials
